In such instances, you release iD Tech and its employees from any and all responsibility and liability for accounts created by your student without iD Tech’s knowledge.
Game Ratings: iD Tech takes its corporate responsibility and iD Tech family values very seriously. However, we cannot guarantee that younger students at iD Tech will avoid all contact with or mention of games rated "T" for Teen, or "M" for Mature. iD Tech will make a concerted effort to minimize both direct and indirect exposure to any games not rated for a student’s age group. Students attending courses designed for older ages have a greater chance of being exposed to materials rated for that older age group. If a student is attending a course for ages 13+, they may be exposed to games rated "M" for Mature by the ESRB (Entertainment Software Rating Board). You voluntarily assume any and all risks, known or unknown, associated with your student’s exposure to game content at an iD Tech Program.
